But I put goodyear silent armor AT's on my truck, 275x70x18, e Load Range...as you can imagine, at 50psi truck is just a TAD rougher than stock.

At 35psi, it rides almost like stock...

I have folks telling me I can run 35psi, folks saying 50psi is minimun, I just called goodyear twice, spoke to 2 different support folks, and one said 35psi is fine on a 1/2 ton truck and another that said 50 is minimun.

Originally I had them at 40psi and I didn't think the tire handled very well, but that may have very well been my imagination. After having them at 50psi for about a month, I took the truck to the dealer for a free oil change (had to preface the free part. lol) and they aired my tired down to stock PSI...at first I was kinda pissed but after driving them there they felt just fine and truck was much more comfortable.

WHAT DO I DO???

Is 35psi SAFE??
Will they wear early?
Any problems with running 35psi on an E Load Range Tire??

HELP!!!????? I need a straight answer.

BTW, I was on 95 Sount the other day, while at 50psi, and when the truck hit about 85mph it felt a little squirrely, almost like on ice skates a little...anyone else noticed this with these tires?

I don't have those tires, but what do they say on the tire?

50 is too high for an unladen truck.
36 is probably okay running empty.

I don't have those tires but I'll chime in with an experience I know some others have had...

The rear tires on my truck wore down in the center at a rate that just amazed me. I always checked the pressure and kept it at the reccomended psi, but they wore as if they were severely over-inflated. This wear happened so fast that I decided not to rotate and at least save the 2 in the front. Nissan would not help, so I took the truck to a Goodyear dealer and their first comment was that they had been over-inflated. Then they took a guage to them and decided they were actually at less psi than the tire itself even suggested, so they gave me a sweet deal on a couple new tires to tide me over until my purchase of new Revos.

Anyway, I'm relaying this to suggest that the above post about 50psi in an unladen truck is good advice...you may well see this wear pattern if you do this. I guess they are just so light in the rear that even standard pressure is too much.

The tire sidewall probably states the maximum psi, like every other tire in existence.

Maximum psi does not often equal recommended psi. I'm not sure how people always get those two concepts directly linked.

To the OP, take the recommended psi listed in your door jam, and the max psi listed on the tire sidewall, and experiment within that range until you find the ride/mileage/tire wear you like. Air up in the range if you plan to tow anything of large magnitude.

Personally, I have e-range BFG's, and run 40 psi.

Just my $.02.

Run them where you want them, just keep an eye on them. Most people don't read, the tire states the MAX pressure not a recommended pressure. The tire shops here keep airing mine up to 50-55 psi then they ride like crap so I air them back down to 40-psi. I don't haul anything heavy and will air them up when I need to rent a Bobcat or something so I like them better at 38-40psi for DD.

My stock ContiCRAPS did the same dam thing. PSI was perfect but center of the tire wore out so freakin fast I was amazed. those tires are JUNK. glad I got new rims/tires now.

as for the PSI to run. I agree with running what the door jam says. Thats what its there for, and most likely will be good for the size you have. 50 is WAY to much in my book. and how people say to run what the tire says baffles me? does the word MAX next to it mean anything to you? haha.

Keep in mind, this is an E-Load Range Tire, so its built differently than a P rated tire.

n0tty4titan · Feb 18, 2009

understandable. But an E rated tire on a 1/2ton truck is alittle much. 40psi would be max Id say. E is for heavier trucks, ours dont way that much, so running lower is gonna be your best bet. Trial and error unfortunatly is gonna be your best way. try different psi for a few weeks see how it does with handling and treadwear. If its wearing out on the sides, then air up, middle wear air down.

Please show me one piece of documentation that shows a 50-psi MIN on a LIGHT truck tire. I have yet to see one and find it difficult to believe, especially on just an A/T. I've seen those tires and read over the sidewall and I'll bet you that 50-psi is the MAX and not the MIN.

My suggestion is: Read your sidewall then go down and b*tch slap the idiot who told you it's the Min.

I'm just telling you what goodyear customer support said...I'm just relaying information.

That's obvious, it's just frustrating that you're getting such wrong information enough to cause uncertainty. It's not rocket science, those morons on the phone should know better. If you want to hear from an expert, send a PM to Discount Tire Direct. Those guys know tires better than the knuckleheads you talked to.

One of the things I was trying to get across in my above thread is that even the door label pressure that is reccomended for the rear was too high, at least in my situation and with the stock goodyears. The thing is, I have a 150lb dog box in the back of my truck 99.99% of the time, so it's not like I'm running around empty, either. There is almost always almost 100lbs of other stuff as well, so I just don't understand why this happened.

No matter what you do, don't expect Nissan to warranty any tire problem on the stock tires. You are on your own. Maybe if you made a daily stop at the dealer for them to verify that your pressure is at the rating on the door, but even then I think they don't cover tires as policy.

So far so good on the revos! Though I'm a little dissapointed in their snow traction, they are TREMENDOUS in wet conditions, especially something that would have hydroplaned my goodyears.
